6. Connectors
This chapter specifies the details of the connectors on the EPC-2. With one
exception, the miniature parallel-port connector on the EPCÄ2x, all connectors
are identical to the standard connectors on IBM PCs.
In the case of the EPC-2x, see the separate manual on the specific EXM for its
connector definitions.
Pins are labelled from the point of view of looking into the front of the
connector on the EPC-2.

On the EPC-2x, the .i.LPT1; .i.parallel port; connector is a miniature connector
compatible with the 3M 10320 plug. The definition of this connector is shown
below. Note that the .i.adapter cable; provided converts this connector into a
standard DB-25 LPT1 connector as described above.
